Abstract Ecological data are collected over vast geographic areas using digital sensors such as camera traps and bioacoustic recorders. Camera have become the standard method for surveying many terrestrial mammals birds, but trap arrays often generate millions of images that time‐consuming to label. This causes significant latency between collection subsequent inference, which impedes conservation at a time ecological crisis. Machine learning algorithms been developed improve speed labelling...
Abstract Recent seizures of illegally held wildlife indicate a mounting global trade in pangolins involving all eight species. Seizures traded African are increasing as wild populations Asian species decline. We investigated and law enforcement efforts Gabon; country likely to have intact three the four pangolin. compared village sales chains between 2002‐2003 2014. Hunters reported be most frequently requested 2014, value had increased at every point along their chain. In Libreville, giant...
The white-bellied pangolin (Phataginus tricuspis) is the world's most trafficked mammal and at risk of extinction. Reducing illegal wildlife trade requires an understanding its origins. Using a genomic approach for tracing confiscations analyzing 111 samples collected from known geographic localities in Africa 643 seized scales Asia between 2012 2018, we found that poaching pressures shifted over time West to Central Africa. Recently, Cameroon's southern border has emerged as site intense...
Abstract Efforts to preserve, protect and restore ecosystems are hindered by long delays between data collection analysis. Threats can go undetected for years or decades as a result. Real‐time help solve this issue but significant technical barriers exist. For example, automated camera traps widely used ecosystem monitoring it is challenging transmit images real‐time analysis where there no reliable cellular WiFi connectivity. We modified an off‐the‐shelf trap (Bushnell™) customised existing...
Modeling fire spread as an infection process is intuitive: An ignition lights a patch of fuel, which infects its neighbor, and so on. Infection models produce nonlinear thresholds, whereby spreads only when fuel connectivity probability are sufficiently high. These thresholds fundamental both to managing theoretical spread, whereas applied more often apply quasi-empirical approaches. Here, we resolve this tension by quantifying in locally, using field data from individual fires ( n = 1,131)...
In light of recent publications (e.g. Lam et al., 2020; Shang 2020) that indicate a link between pangolin and bat coronaviruses related to SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), we believe observations pangolins bats sharing burrows in Lopé, Central Gabon, is general interest. Our were made during an ecological spatial movement study the giant pangolin, Smutsia gigantea. We used direct animal tracking, telemetry 30 camera traps mature male northern part Lopé National...
In this investigation, optical (SPOT-7 NAOMI), airborne LiDAR, and PolInSAR L-band data, along with forest inventories, were employed to develop models for estimating total dry aboveground biomass (AGB) over the tropical forests in Congo Basin (Gabon) of Central Africa. Remote sensing-based variables like texture (from SPOT), median canopy height LiDAR), backscattering coefficient surface heights PolInSAR) used estimate AGB. These individually (or combined) AGB based on multivariate adaptive...
The Conference of Parties the Convention on International Trade in Endangered Species Wild Fauna and Flora (CITES) provides platform for global collaboration international trade endangered species. Only four CITES CoPs have ever been held Africa, including 2016 17th (CoP17) Johannesburg, South Africa. African nations recognize that illegal wildlife is now a major threat to environmental integrity, undermines good governance, threatens security reduces revenue from sustainable economic...
Abstract Ecological data are increasingly collected over vast geographic areas using arrays of digital sensors. Camera trap have become the ‘gold standard’ method for surveying many terrestrial mammals and birds, but these often generate millions images that challenging to process. This causes significant latency between collection subsequent inference, which can impede conservation at a time ecological crisis. Machine learning algorithms been developed improve camera processing speeds,...
